If the SYSREF Delay is set according to page 71 of PG066, the data obtained may be jumbled. Since M * F = 32, I set BUF_FILL to be at 0x8 ~ 0x18. Is this not enough? Is there any order to set? The SYSREF Delay is configured after the link is established in JESD204B subclass 1.
I have attached the FFT results when it works without problems and when it becomes strange. I'd appreciate it if you could give me some advice.
